LIGHTING FIXTURE FOR SHOW CASES AND THE LIKE.

Application filed November 25, 1921.

To all whom it may concern:

Be it known that 1, DAVID BILLER, a citizen of the United States, and resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements. in Lighting Fixtures for Show Cases and the like, of which the following is a specification containing a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention relates to improvements in lighting fixtures for show-cases and the like, and has for its primary object a lighting fixture which can be readily attached and detached to a show case or similar structure, and in which an angle of inclination or illumination can be adjusted to meet the different requirements.

A further object is to construct a light ing fixture having a removable reflector, the lighting unit. being attached to the reflector.

In the drawings,

Fig. l is a side elevation of my. device. showing the same attached to a show case in which the top and sides are of plate glass.

Fig. 2 a similar View in which the top and. sides of the show case are secured in wooden frames.

Fig. 3 a front elevation showing the method of maintaining my units in multiple.

Fig. 4 a side elevation of the reflector. showing the manner of attaching the lighting socket and frame.

Fig. 5 a plan view of my reflector viewing the same on the interior.

Fig. 6 a cross section showing one method of securing the reflectorwithin the fixture.

Fig. 7 a similar. view, showing another method.

In the construction of my device I employ a casing or housing having a back 8. a front 9, and end walls 10 and 11. Through the end walls is formed an opening and con centric with this opening and secured to the end walls is a ring 12 in which a set screw 13 is located. This ring is adapted to receive the pipe or conduit 14- through which electric conductors 15 are threaded. These conductors passing through the opening formed in the walls 11 and 10 so as to form a continuous circuit through the individual fixtures. irrespective of the number employed. The lower edge of the wall Serial No. 517,530.

8 is bent upwardly and inwardly, so as to form a hook 16, andwithin this hook, the lower end of the wall 17 of the reflector is placed. The reflector is also provided with a curved wall 18. The walls 17 and 18 are connected together by a Wall 19. This wall is provided with an opening 20 through which a pipe or nipple 22 projects. One end of this nipple being secured within the electric socket 23. The socket is secured by means of a lock nut 24:, which is placed on the opposite side of the wall 19, thus securely holding the socket in place. The wall 9 of the casing is curved and has its end folded over. This may be either done as illustrated in Fig. 6, or a bead may be formed as illustrated in F ig. 7. Secured to the inside of the wall 9 are a plurality of strips 25. These strips are used only with the structure in Fig. 6, and are adapted to be bent around the lower edge of the wall 18 to secure the reflector in place. Secured to the wall 8 are strips 26. These may be secured either by riveting or spot welding. That portion of the strips extending" above the housing are provided with openings 27. (see Fig. 3,) and are for the purpose of securing a housing when a show case having a wooden frame is used. The lower por tions of the strips 26 are adapted to be bent as illustrated in Figs. 1 and 2, so as to form a rest against the front glass of the case which governs the inclination of the fixture. This inclination may be varied by bending the portion of the strip acting as a rest. vVhen the device is attached to a show case having a wooden frame, screws 'are inserted through the openings 27, but when attached to a show case having no frame, the strips 26 are inserted between the top and front of the glass composing the case and bent over. This is clearly illustrated in 1. It will be noted from Figs. 6 and 7 that when the reflector is in place, a passage or conduit 28 is formed between the joining 100 edges of the walls 8 and 9 of the casing and the wall 19 of the reflector, and within this conduit an electric conductor extends. In assembling my device the socket 23 is first secured to the reflector. 29 having been previously attached to the socket. The housings are then assembled or connected together by means of pipes or conduits 15. The conductors 15 then drawn entirely through the assembled fixtures. 110

The conductorsl Connections are then made between the conductors and 29. The various housings are now ready to receive the reflectors. This is accomplished by placing the wall 17 of the reflector within the hook formed on the rear wall 8. The reflector is then pushed upward and inward in the housing and after it is firmly set therein, the strips are bent around the lower edge of the wall 18 securing the reflector in place. This bending of the strips 25 is unnecessary where the structure shown in Fig. 7 is used. When the reflector is pressed home in this structure, the lower edge of the reflector wall 18 springs past the bead formed on the lower edge of the housing wall 9, and holds the reflector in position.

WVhen it is desired to remove the reflector for any purpose in the structure shown in Fig. 6, it is only necessary to bend down the strips 25 while in the structure shown in Fig. 7, a screw driver or similar tool can be inserted and the reflector sprung out of the casing. l p I Having fully described my lHVGllillOIl, what I claim is:

1. A lighting fixture for show cases and the like comprising a housing having end walls, a reflector removably located in said housing, a lamp socket secured to said reflector, means secured to said housing for contacting with the edges of said reflector to hold the same therein, and pliable strips secured to the housingand resting against the front of a show case for regulating the inclination of the housing when secured therein.

2. A lighting fixture for show cases and the like, comprising a housing having end walls, a reflector adapted to be sprung within said housing, a lamp socket secured to said reflector, means carried by the housing for holding the edges of the reflector, and means secured to said housing for securing the same to a show case, said means also adapted to rest against the front of the show case for regulatingthe inclination of the housing.

3. A lighting fixture for show cases and the like, comprising a housing having end walls, a reflector having open ends adapted to be sprung within said housing, a lamp socket secured to said reflector, and pliable strips secured to the housing, the upper end of which is adapted to secure the housing within a show case, and the lower end thereof to adjust the housing to and from the front wall of said case.

4. A lighting fixture for show cases and the like, comprising a housing having end walls, a reflector having open ends detachably secured within said housing, a'lamp socket secured to said reflector, strips carried by said housing for holding the reflector therein, means carried by the end walls of the housing, whereby a plurality of housings can be assembled together in spaced apart position, and pliable strips secured to said housing, said strips adapted to secure the housing within a show case, and also to adjust the housing to and from the front wall thereof.

5. A lighting fixture for show cases and the like, comprising a housing having end walls provided with a perforation, a collar surrounding said perforation, a reflector having open ends detachably secured within said housing, a lamp socket detachably secured to said reflector, pliable strips carried by the housing for securing the same within a show case, and regulating its inclination to the front wall thereof, and means adapted tobe secured within said collar for assembling a plurality of housings together in spaced apart position.

6. A lighting fixture for show cases and the like, comprising a series of housings provided with end walls having openings formed therein, rings provided with screwthreaded openings secured to the end walls and surrounding said openings, reflectors sprung into said housings and held therein by the resiliency of the material out of which the reflectors are formed, sockets detachably carried by the reflectors, a series of pipe sections located in said rings, and set screws for connecting and disconnecting said housings to said pipe sections.

In testimony whereof, I have signed my name to this specification.

DAVID BILLER.
